my problem mainly was fatigue, when I used an aluminum pressure cooker several times a week for a while I was so fatigued I almost couldnt leave the house (ended up having to rest just from walking to car, then before venturing into store etc.)
I also have had decreasing memory (long and short term), muscle aches and joint stiffness. The only thing that I cant tell improvement yet is the memory. Im sure there were other things wrong, I just havent noticed or narrowed it down to the mercury yet. I figure my numbness in arms and legs is from the fact I have low blood pressure/thus circulation and also easily dehydrate(also possibly a cause of much of my stomach and back ache problems)
The white on tongue might mean your body is detoxing somethign as I went on a Water Fast last year and that is common when detoxing. Fast didnt do as much as I liked but it was months before I had mercury out, which I had great results from removing over thanksgiving weekend!
I wish I had found these forums and aharleygyrl's website years ago!
